CASH REGISTER AND RECORDER.

SPECIFICATION forming part of Letters Patent No. 474,278, dated May 3, 1892. Application filed November 11, 1891. Serial No, 411,601. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT R. ABBOTT, of Boston, in the county of Suffolk and State of Massachusetts, haveinvented a new and Improved Oash Register and Recorder, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved cash register and recorder which is simple and durable in construction, very effective in operation, not requiring frequent resetting, and is arranged to add up the various sales made, at the same time showing the amount of the individual sale and delivering a check or ticket on opening the moneydrawer, and also ringing a bell.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a transverse section of the improvement. Fig. 2 is a sectional front view of the same on the line 2 2 of Fig. 1, Fig. 3 is a sectional plan View of the same on theline 3 3 of Fig. 1, and Fig. 4 is a transverse section of the adding device on the line at l of Fig. 3.

The improved cash register and recorder is provided with a suitably-constructed casing A, in which are mounted to slide transversely sets of keys B B B having their bearings in the front A of the casing and in a transverse bar A as is plainly shownin Fig. The sets of keys are preferably arranged in tiers, located one above the other, each key being provided at its outer end with a finger-piece marked with a numeral, the sets of keys B being for even numbers, representing cents, the keys B for odd numbers, also representing cents, and the keys B with numbers for representing dollars. Each key is provided on the inside of the casing A with a pin B engaging one arm O of a bell-crank lever O, fulcrumed on a transversely-extending rod 0*, secured in the sides of the casing A. The other arm 0 of each bell-crank lever C is pivotally connected with an upwardly-extending rod D, formed at its upper end into a plate D,

carrying a numeral on both sides corresponding to the numeral of the respective key with which its bell-c *ank lever is connected. The plates D when moved to an uppermost position are visible from the outside of the casing through panes of glass A and A arranged transversely in an offset A, secured on top of the casing A. The panes of glass A and A are located opposite each other in opposite sides of the plate D, so that an operator manipulatingthe keys B B B can see the nu meral displayed on the respective keyboard and the purchaser can also see the amount of his purchase registered through the pane of glass A. Each rod D is also provided with a wedge D located below the plate D and adapted to pass between transversely-extending bars D and D", of which the bar D is mounted to slide horizontally in suitable bearings A, formed on theinside of the sides of the casing A. The other bar D is fixed in the sides of the casing, and when the rod I) is moved upward its wedge D presses the movable part D outward against the tension of springs D held in the bearings A. hen the base of the wedge D has passed the bar D then the latter closes under the base of the wedge D thus locking the rod D in an uppermost position, with its plate D in the offset A to permit its numeral to be seen from both sides.

In order to open the bar D to permit the rod D to drop into a normal position, wedges D are employed adapted to pass between the movable bar D and the fixed bar D" from above and at their ends, the said wedges D being held on rods D extending vertically and pivotally connected at their lower ends with arms E, secured on a shaft E, mounted to turn in suitable bearings in the sides of the casing A. The shaft E carries arms E extending upward and connected with each other by a transversely-extending rod E adapted to be engaged by the inner ends of the keys B B B In order to hold the arms E and E as well as the shaft E in a normal position, aspring E is employed, pressing on the arms E so as to hold the rod E in contact with the inner ends of the keys B B 3 WVhen one of the keys is pressed, the rod E is caused to swing inward, so that the arms E move likewise and turn the shaft E, which swings the arms E downward, thus drawing the rods D in a like direction and engaging the wedges D with the movable bar D and the fixed bar D, so as to press the movable bar D outward to permit the rod D, which was in an uppermost position, to drop downward. Suitable weights C may be held on the arms 0 of the bellcrank lever C, so as to insure a returnmovcment of the respective bell-crank lever and the key connected with it.

On one of the arms E is pivoted a sprhigpressed pawl E, adapted to engage an arm E secured on the shaft carrying the striker E adapted to sound a bell E, supported in the casing. Thus when a key is pressed inward the arm E, carrying the pawl E acts on the arm E so that the striker E is moved outward away from the bell E?, and when the pawl E has passed the arm E the striker simply returns, by the action of a spring or other means, and sounds the bell E. The arm E is also pivotally connected by a link F with a latch E, pivoted at F in the casing A and formed on its top with a notch E adapted to engage a fixed bar F", held on the rear end of the money-drawer F mounted to slide in the bottom of the casing A and adapted to be drawn open by the action of a coiled spring F, attached byone end to the rear end of the said drawer and by its other end to the front of the casing A. The free end of the latch F is beveled, as is plainly shown in Fig. 1, so that when the drawer F is pushed shut against the tension of the spring F then the fixed rod Etravels up the bevel and finally engages the notch E so that the latch F locks the drawer E in position.

On the under side of each key, within the casing A, is pivoted a spring-pressed pawl G, engaging a ratchet-wheel G, mounted to turn loosely on a transversely-extending rod G held in the sides of the casingA. Each ratchetwheel G carries on one face a wheel G below which is located a smaller wheel G", between which and the wheel G passes a strip of paper G unwinding from a roll of paper G, mounted to turn in the rear part of the casing, as is plainly shown in Fig. 1. The strip of paper Gr after leaving the wheels G and G extends upward and overatype-wheel II, secured on a shaft H, mounted to turn in suitable hearings in the sides of the casing A, one end of the said shaft extending to the outside of the casing and carrying on its outer end a knob or handle 11 for turning the shaft. On the knob or handle is also secured a pointer H indicating on a dial ll attached to the outside of one of the sides of the casing A and containing characters corresponding to the characters on the type-wheel, so that the position of the type isindicated by the pointer H on the corresponding character of the dial H Each type-wheel H is made of two wheels 11 and H, of which the wheel H is mounted to turn loosely on the wheel 11 and is provided between each two successive characters with a slot H adapted to be engaged by a lug H projecting from a rod I1, mounted to slide transversely in the sides of the casing A and under the control of the operator. \Vhen the lugs H engage the notches in the wheels II, the latter are locked in place, and when the shaft H is turned only the wheels 11 turn. lVhen the bar H is shifted transversely by the operator to one side and when the moneyd 'awer E is opened to permitthe operator to take hold of the said bar, then the lugs H are disengaged from the notches H and the wheels H are free to turn with the wheel 11 when the shaft H is rotated. The wheel H is formed on its rim with numerals 1 to 31 for indicating the day of the month, and the wheel 11 is formed at its rim between the notches with the name of the month, the twelve months of the year being indicated on the entire rim of the wheel. The paper passes under a protecting-plate I, located above the wheels If and also passes over a transvcrsely-arranged fixed bar I,located on one side of the wheel and having its front surface ext-ending vertically and tangentially to the rim of the wheel. On this fixed bar I are characters indicating amount of sale. Opposite this bar I and the characters on the wheels II and I1, directly above the said bar, is arranged a platen B"one for each key B 1 and the corresponding type-wheel 11. Thus when a key is pressed inward the platen 13 moves against the paper extending on the right-hand side of the wheels and over the bar 1, so that the paper is pressed upon the characters on the wheels 11 and 11" of the respective type-wheel and upon the type-bar I, so that the characters on the latter, as well as the type on the respective type-wheel, are printed on the paper.

Directly over the platen 13" of each lever is arranged a knife 13, adapted to cut the paper directly above the characters on the wheels 11 H, from which characters the impression had been made, the knife ll passing upon the paper and cutting the same on the rims of the wheels. The ticket or coupon thus cut off the strip of paper G drops downward into the nioney-drawer F, then in an open position. The inward movement of each key feeds the strip of paper G forward over the respective type-wheel II by the action of the pawl G turning the ratchet-wheel G, and consequently the wheel G. The paper passing between the latter and the wheel G" is thus pushed forward over the type-wheel, the amountof forward feed corresponding to the space occupied by the front face of the typebar 1 and one set of characters on the two wheels II and II.

In order to record and add up the sales in a stated time, the following device is provided, being actuated from the keys 1 3, and B The device is provided with a suitably-constructed casing J, arranged on one side of the casing A and provided with avertical bar J, mounted to slide in suitable bearings in one side of the casing A. ()n the inner face of this sliding bar J are arranged the pins J and J located one above the other, and similar pins J 2 J 3 are arranged in a bar J mounted to slide vertically in the other side of the casing A and directly opposite the sliding bar J. Springs J press on the lower ends of the sliding bars J and J, so as to hold the same in a normal position. The pins J J in the two sliding bars J and J' are adapted to be engaged by thebeveled ends of the pawls K and K, respectively, pivoted on the levers K and K respectively, fulcrumed at K and K on the sides of the casing A. The pawls K and K are spring-pressed, so as to engage with their beveled ends the respective pins J 2 and J the pawls being prevented from slipping upward by fixed bars J attached to the inside of the casing A, across the bars J and J The levers K on the opposite sides of the casing A are connected with each other at their lower ends by a-transverse bar K, adapted to be engaged by projections or lugs B on the keys B and B so that when one of the latter is pressed this projection presseson the bar K thus imparting a swinging motion to the levers K which by their pawls K press on the pins J thus imparting a downward sliding motion to the bars J and J; consequently to the easing J and its contents. The levers K are similarly connected with each other by a bar K which is actuated by the projections or lugs B on the keys B, so that when one of the latter is pressed inward the levers K are caused to swing, and the pawls K, acting on the pins J press the bars J J downward, thus moving the casing J in a like direction.

In the two bars J and J are mounted to turn the gear- Wheels L and L, extending throughout the width of the casing A, as is plainly shown in Fig. 2. The gear-wheels L and L are adapted to be engaged by segmental gear-wheels L and L respectively, secured on shafts L and L respectively, mounted to turn in suitable bearings in the sides of the casing A. The segmental gearwheels L are pivotally connected with the set of keys B and the other segmental gearwheels L are pivotally connected with the keys B and B, as is plainly shown in Fig. 1. Thus when a key B is pressed the levers K and pawls K cause a downward swinging motion of the bars J and J, so that the gearwheels L and L move downward such a distance that the gear-wheel L is engaged by the segmental gear-Wheel L connected with the pressed key B, the said key imparting a swinging motion to the said respective segmental geanwheel L so as to turn the gear-wheel L. In a like manner, when one of the other keys B is pressed,the levers K are caused to swing, and by their pawls K engaging the pins J cause a downward swinging motion of the bars J and J so that the gear-wheels L and L are moved into a lowermost position, the

gear -wheel L being engaged by that segmental gear-wheel L receiving a swinging motion from the pressed key of the set of keys B. Then the pressure on the pressed key ceases, the parts are returned to their proper positions by springs connected with the levers K and K as is plainly shown in Fig. 1. The pawls K and K are thus moved outward away from the pins J and J so that the bars J and J return to their normal position by the action of the springs J One of thelevers K is also pivotally connected by a link N with a slide mounted to slide horizontally in suitable guideways N attached to the inside of one of the sides of the casing A. The slide N is provided on its under side with rackteeth N adapted to mesh in a gear-wheel N, attached to a shaft N, mounted to turn in suitable bearings in the bar J below the gearwheel L, previously mentioned. lVhen the lever K receives an inward swinging motion by pressing upon one of the keys of the sets of keys B, then the link N pushes the slide N 2 rearward, so that the rack-teeth N move to the left above the gear-wheel N which latter is then in a lowermost position, and is consequently not acted on by the rack-teeth N .Vhen the lever K returns to its normal position and the bars J and J slide upward, then the slideNis on its return movement, and by its rack-teeth N engages the gear-wheel N thus rotating the same and its shaft N Each of the pawls K and K is provided with a recess K and a bevel K extending forward from the recess, as is plainly shown in dotted lines in Fig. 1, so that when the levers K and K have moved into their innermost positions the pins J 2 and J engage the said recesses K and the return movement of the bars J and J takes place, this return movement be ing suddenly caused by the action of the springs J When a key 13 1s pressed, its lug B acts on the bar K of the levers K so that the pawls K of the latter press the bars J and J downward to move the gear-wheel L into the path of the segmental gear-wheel L which latter then receives a swinging motion by the pressed key B The shaft of the gearwheel L operates the mechanism for adding dollars, while the shaft of the gear-wheel L serves to add the tens both of even and uneven numbers from the keys B and B. In addition, the gear-wheel N actuated by the key B, carrying uneven numbers, adds the unit 5 whenever a key B is actuated, it being understood that the keys B and B only move tens, and in order to make up for the fraction of a unit 5 the keys B actuate the units gear-wheel N One of the keys B is not connected with the segmental gear-wheel L and only acts on the bar K of the levers K so that the slide N only is actuated, and when the lever K returns the rack-teeth N actuate the units gear-wheel N so that an addition of only five cents is made.

The two keys B and B, carrying the numerals 10 and 15, respectively, are connected with segmental gear-wheels L having a likenumber of teeth, so that when either of the said two keys is pressed the gearwheel L is turned the same distance; but, in addition, when the key B is pressed, the units gearwheel N is turned, so that the sum of 10 and 15 is added in the adding-machine. \Vhen the key B of the numeral 10 is pressed, the gear-wheel L is turned the same distance as when the key B, having numeral 15, is actuated, so that, as far as the gear-wheel L is concerned the latter is turned the same distance on pressing either of the keys B and B, bearing the numerals 1O and 15, respectively. The pressing of the key B with numeral 10, however, does not actuate the units gear-wheel N, so that only ten cents is added, while when the key B, carrying the numeral 15, is pressed, ten is added by the gear-wheelLand five bytheunits-wheelN A like arrangement is made on the other keys that is, the key B, carrying, for instance, the numeral 30, when pressed turns the gear-wheel L the same distance as when the key B, carrying the numeral 35, is pressed; but the latter key also actuates the units gearwheel N so that an addition is actually made in the adding-machine when 'LlTB key B, having numeral 85, is pressed.

It is understood that the number of teeth of the several sets of segmental gear-wheels L increases according as the value of the n uinerals increases, so that the gear-wheel L is turned a corresponding distance to properly add up the amount indicated by the key pressed. The upper set of keys B actuates the levers K for shifting the bars J and J into a lowermost position for the respective segmental gear-wheel L to turn the gear-wheel L. The segmental gear-wheels L for the several keys B have such a relative number of teeth as to add the proper amount in dollars.

The shaft N carrying the units gear-wheel N extends into the inside of the casing J and carries thereon a gear-Wheel N in mesh with a gear-wheel N secured 011 a transversely-exten'ding shaft 0, mounted to turn in suitable bearings in the casing J. On the shaft 0 is secured a sprocket-wheel 0', connected by a sprocket-chain O with a sprocket-wheel 0 formed on the hub of the unitswheel 0 provided on its rim with the successive numerals 0 to 9, adapted to appear in an opening J in the front of the casing J. The units-wheel O is mounted to turn on the hub P of the tensavheel P, also provided with the numerals O to 9 in succession and arranged alongside the units-wheel O. The two wheels P and O" when read together indicate cents. The tens-wheel P is mounted to turn on the hub Q of the units dollar-wheel Q, having numerals0 to 9 in succession on its rim, the said units dollar-wheel being arranged next to the tens cent wheel P. The units dollar-wheel Q is mounted to turn loosely ona shaft R, extending transversely and carrying the tens dollar-wheel R, arranged next to the units dollar-wheel Q.

On the hub P of the tens cent-wheel P is formed or secured a sprocket-wheel P over which passes a sprocket-chain P also passing over a sprocket-wheel P, secured on the shaft L of the gear-wheel L, previously mentioned. Thus, when the latter is rotated, its motion is transmitted by the sprocket-wheel P, the sprocket-chain P and the sprocketwheel P to the tens cent-wheel P, to properly indicate the amount of the respective key pressed. In case a key B is pressed with an odd numeral the shaft L as well as the shaft 0, is actuated in the manner previously described, so that the tens and the units are added on the wheels P and 0.

On the shaft L is secured a star-wheel P having ten teeth adapted to be engaged by a pin 0 on a wheel 0", attached on the shaft 0. Thus one complete revolution of the wheel 0 moves the wheel P the distance of one tooth, thus actuating the shaft L and the tens-wheel P to indicate the proper amount. The hub Q of the units dollar-wheel Q carries a sprocket-wheel Q over which passes a sprocket-chain Q, also passing over a sprocket-wheel Q, secured on a shaft Q, extending transversely and mounted to turn in suitable hearings in the casing J The shaft carries a bevel gearwheel Q in mesh with a bevel gear-wheel Q secured 011 a shaft Q extending angularly at one side of the casing J, and carrying at its upperend a bevel gearwheel L in mesh with a bevel gear-wheel L attached to the shaft L of the upper gearwheel L, previously mentioned. Thus when the latter is actuated by pressing one of the said keys B the motion of the said gearwheel L is transmitted by the bevel gearwheel L to the bevel gear-wheel L and to the shaft of the latter Q The motion of the shaft Q is transmitted by the gear-wheels Q Q to the shaft Q which, by the sprocketwheel Q, the chain Q and the sprocketwheel Q imparts a rotary motion to the units dollar-wheel Q.

On the shaft Q is secured a star-wheel S, adapted to be turned by a pin P on the wheel P previously mentioned, it being understood that every revolution of the wheel P moves the star-wheel S the distance between two teeth. Thus when the shaft L makes one complete revolution the shaft 0 is rotated, so that the wheel Q makes onetenth of a revolution, and the next following numeral is brought into the opening J thus registering the one hundred cents or one dollar from the wheels P and O".

. On the starwheel S is secured a pin S, adapted to engage a star-wheel S secured on a shaft S mounted to turn in suitable bearings in the casing J, the shaft S carrying a sprocket-wheel S, connected by a sprocketchain S with a sprocket-wheel S, secured on the shaft R, carrying the tens dollar-wheel IIS R, previously mentioned. Each complete revolution of the wheel S moves the starwheel S around one-tenth part, so that the shaft S is rotated and its motion is transmitted to the tens dollar-Wheel R, which latter thus registers the proper amount.

The star-wheel S is provided with a pin S adapted to engage a star-Wheel T, also having ten teeth and secured on a shaft T, mounted to turn in suitable hearings in the casing J, the said shaft carrying a sprocket- Wheel T over which passes a sprocket-chain T also passing over the sprocket-wheel T, secured on the hub T of the hundreds dollar- Wheel T provided with successive numerals up to 10 011 its rim and located next to the tens dollar-wheel R. The hundreds dollarwheel T is mounted to turn loosely on the shaft R, as is plainly shown in Fig. 2. hen the wheel S has made one complete revolution, its pin S moves the star-wheel T the distance between two teeth, thus turning the shaft T. The movement of the latter is transmitted by the sprocket-wheels T and T and the sprocket-chain T -to the hundreds dollar-wheel T which is thus turned to bring the next following numeral into the opening J On the face of the star-wheel T is secured a pin T adapted to engage at every revolution a star-wheel U, having ten teeth and being secured on a shaft U, also mounted to turn in the casing J. On the shaft U is secured a sprocket-wheel U over which passes a sprocketchain U also passing over a sprocket-Wheel U, formed on a hub of the thousands dollar-wheel U mounted to turn loosely on the hub T of the hundreds dollarwheel T The thousands dollar-wheel U is arranged alongside the hundreds dollar-wheel T, and'its numerals also appear in the opening J hen the wheel T makes one revolution, its pin T moves the star-wheel U the distance between two teeth, the movement being transmitted to the shaft U and from the latter by the sprocket-wheels U and U" and sprocket-chain U to the thousands wheel U so that the latter brings the next following numeral into the opening J Thus it will be seen that when the key B, marked with numeral 5, is pressed, the lever K by the rack-teeth N actuates the wheel N and the latter by its connection with the units cent-wheel 0 moves the latter to bring the next following numeral into the opening J When a key B is pressed, the lever K is actuated to move the slide J into proper position and also to actuate the corresponding segmental gear-Wheel L to turn the gear-wheel L the proper distance. The movement of the gearwheel L is transmitted by the shaft L and the sprocket-Wheel P chain P and sprocketwheel P to the tens cent-wheel P in the manner above described, so that the proper numeral corresponding to the numeral of the key pressed appears in the opening J The amount of the units-wheel 0" stands beside it,

and consequently the total amount appears in the opening J When a key B is pressed, then the shafts L and O are actuatedthat is, the shaft L is actuated on the inward movement of the key B and the shaft 0 on the return movement of the same. Thus the proper amount on the tens cent-wheel P is registered and the units added on the wheel 0''. hen the amount is more than one dollar, the dollar-wheel Q is actuated from the shaft L in the manner previously described. Then a dollar-key B is pressed, the gearwheel L is actuated and its motion is transmitted to the shaft Q and from the latter to the dollanwheel Q, as above described, so that the proper sum is added on the said wheel and the total amount appears in the opening J The tens dollar-wheel R is actuated from the shaft Q in the manner above described, and in a like manner the hundreds and thousands dollar-wheels to register the proper total amount. Suitable springs may be employed in the casing J to hold the indicating-wheels 0 P, Q, R, T and U in position to pre vent their accidental turning. It will further be seen that whenever the keys 13,]3, and B are in their normal outermost position the adding deviceis completelydisconnected from the said keys as the gear-wheels L, L, and N are disengaged from the segmental racks L and L and the rack-teeth N respectively. The casing J, with the adding mechanism, is moved down in position whenever a key is pressed and is actuated during the time the key is pressed and returned in case a unit is to be added. The casing J moves back to its normal uppermost position when the respective key is returning.

It is understood that this machine when actuating the keys 13,13, and B indicates each individual sale, and also shows the total amount of the previous sales. The device also displays a tablet showing the amount of the sale, at the same time dropping the previously-displayed tablet. on a strip of paper and cuts the paper to drop a coupon or ticket with the amount of the sale, date, &c. lVhen a key is pressed, the money-drawer is opened and a bell is also sounded.
